Physicists settle debate over how exotic quantum particles form
PHYS.ORG New research by physicists at the University of Chicago settles a longstanding disagreement over the formation of exotic quantum particles known as Efimov molecules. 2 hours
Neutron-rich nucleus shapeshifts between a rugby ball and a discus
PHYS.ORG An international team led by scientists from IPN Orsay (CNRS/Université Paris-Sud), CEA, and RIKEN (Japan) has performed the first spectroscopy of the extremely neutron-rich isotopes krypton 98 and... 3 hours
Quantum thermometer or optical refrigerator?
SCIENCE DAILY In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. 17 hours
Quantum thermometer or optical refrigerator?
PHYS.ORG In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest... 19 hours

Quantum correlations from a room-temperature optomechanical cavity
Science Magazine The act of position measurement alters the motion of an object being measured. This quantum measurement backaction is typically much smaller than the thermal motion of a room-temperature object and thus difficult to observe.... 20 hours
Quantum and isotope effects in lithium metal
Science Magazine The crystal structure of elements at zero pressure and temperature is the most fundamental information in condensed matter physics. For decades it has been believed that lithium, the simplest metallic element, has a complicated... 20 hours

Bug-proof communication with entangled photons
PHYS.ORG Due to the rapidly growing processing power of computers, conventional encryption of data is becoming increasingly insecure. One solution is coding with entangled photons. Fraunhofer researchers are developing a quantum coding source that allows the transport of entangled... 2 days
Prototype device enables photon-photon interactions at room temperature for quantum computing
PHYS.ORG Ordinarily, light particles—photons—don't interact. If two photons collide in a vacuum, they simply pass through each other. 4 days

Shaking Schrödinger's cat
SCIENCE DAILY Frequent measurement of a quantum system's state can either speed or delay its collapse, effects called the quantum Zeno and quantum anti-Zeno effect. But so too can "quasimeasurements" that only poke the system and garner no information about its state. 7 days
How the quantum Zeno effect impacts Schroedinger's cat
PHYS.ORG You've probably heard about Schrödinger's cat, which famously is trapped in a box with a mechanism that is activated if a radioactive atom decays, releasing radiation. The act of looking in the... 1 week
